A study on elemental contents of medicinally important species of Artemisia L. (Asteraceae) found in Pakistan

Journal of Medicinal Plants Research 11/2010; 4(21):2256-2263.


Genus Artemisia is cosmopolitan in distribution and its several species are being used in folk therapeutic treatments worldwide. In this study, elemental compositions of seventeen indigenous species (A. scoparia, A. absinthium, A. indica, A. santolinifolia, A. maritime, A. vulgaris, A. japonica, A. nilagirica, A. herba-alba, A. annua, A. brevifolia, A. moorcroftiana, A. dracunculus, A. roxburghiana and A. dubia) that are commonly used against ailments in Pakistan were studied for the first time through atomic absorption spectrophotometry methods. In this study we observed nine trace elements namely Zn, Cu, Cr, Ni, Co, Cd, Pb, Mn, Fe and four major elements that are K, Na, Ca and Mg in these species. Further it is observed that in few sepses the concentration of heavy metals are found over and above the normal concentration levels than the international safety standards prescribed for medicinal plants. This study also discusses the impacts of heavy metal toxicity in humans.

    • "Artemisia belongs to the most assorted genus of the family Asteraceae, consisting of over 500 species, with 38 species reported in Pakistan [1]. Various classes of secondary metabolites including oxygenated aliphatic hydrocarbons, phenolic hydrocarbons, polyacetylenes, furans, terpenes, flavonoids, coumarins and alkamides are reported from Artemisia [2].

    ABSTRACT: A new compound (1) (named as artemceramide-B) together with eight known compounds (taraxerol (2), taraxerol acetate (3), β-sitosterol (4), stigmasterol (5), trans-ethyl caffeate, dracunculin (7), scoparone (8) and isoscopoletin (9) were isolated from an ethanolic extract of the roots of Artemisia incisa Pamp (Asteracae). The structures of the compounds were determined through IR, 1D NMR (1 H NMR, 13 C NMR) and 2D NMR (COSY, NOESY, HSQC and HMBC) analyses. Accurate mass analyses were done with EI-MS, ESI-MS and acid methanolysis of compound 1 followed by GS-MS studies. The relative stereochemistry of artemceramide-B was determined by comparing its specific rotation and spectroscopic data with the literature. Compounds 1-9 were tested for their anti-bacterial potential against five bacteria strains; Staphylococcus epidermidis, Staphylococcus aureus, Klebsiella pneumoniae, Bacillus subtilis and Escherichia coli. Compound 1 (new) (MIC: 0.0157, 0.0313 mg/mL) and 7 (MIC: 0.0815, 1.000 mg/mL) showed excellent activities against S. epidermidis and S. aureus while compound 9 showed excellent activities (MIC: 0.0700, 1.234, 1.890 and 2.286 mg/mL) against S. epidermidis, S. aureus, K. pneumoniae and E. coli, respectively. Compound 6 (MIC: 2.000 mg/mL) was found to be active against E. coli while neither of the compounds showed potential activity against B. subtilis.

    ABSTRACT: Digitalis purpurea and Digitalis lanata are commonly used in treatment of heart diseases, the species has recently introduced for cultivation in the state of Uttarakhand, India. The mineral contents of cultivated plants of these species have to be within permissible limit for its effectiveness. Using inductively coupled plasma mass spectrometry (ICP-MS), this paper describes analysis of selected minerals [viz. Boron (B), Chromium (Cr), Manganese (Mn), Cobalt (Co), Nickel (Ni), Copper (Cu), Arsenic (As) and Lead (Pb)] in various plant parts of D. purpurea and D. lanata at pre- and post flowering stages. Our results revealed that the concentration of B, Cr, Mn, Co, Ni, Cu, As and Pb as 8.16±0.04 to 27.18±1.11, 7.30±0.03 to 21.16±0.20, 62.69±1.45 to 247.27±5.29, 0.65±0.08 to 6.13±0.05, 9.19±0.01 to 16.15±0.05, 0.02±0.0 to 25.27±0.20, 0.83±0.04 to 4.98±0.06 and 4.70±0.02 to 8.19±0.04 ug g-1, respectively. The study reports that the mineral contents were well within the permissible range for medicinal uses. Therefore, the species are recommended for large scale cultivation.
